\l\. An Enquiry into a DifcoVery, /aid to have been 
made by Signor Valfalva of Bologna, of an Ex- 
cretory Duel from the Gland u la Renal is to the 
Epididymis. <By Mr, John Ranby, Surgeon, 

THE late learned Signor Valfalva having fome Time 
ago difcover'd a Veffel, which he took to be an 
Excretory Dud going from the Glandula Renalis, to 
the Epididymis in Men, and the Ovarium in Women; 
anAccount whereof was publiuYd in the Giorn. de Lit- 
terati, 1719. and afterwards inferted into the Thilofo- 
fhical Tranfatlions N°385. I lately procur'd a hu- 
man Body, in order to fearch for it, which I did with 
all the Diligence I was capable of. I was not fo happy 
as todifcover any Dud of this Kind, but,having injeded 
the Aorta, I found the Arteries going to the Glandula 
Renales difpos'd, as hath been represented according to 
the Life, in the annexed Figure. Now whether that 
Branch of the Artery, which from the GlandulaRenales 
goes down on both Sides towards the Tefticies, without 
fupplying any of the neighbouring Parts, might not have 
been miftafcen by the abovementroned learned Anafomift 
for an Excretory Dud, all Arteries being generally in 
dead Bodies free from Blood, and of a whitifh Colour, 
I will not prefume at prefent to determine, for Want of 
farther Experiments.
